Rose plant named ‘POULen007’

ABSTRACT

A new garden rose plant of the hybrid tea class which has abundant dark red flowers, exceptional fragrance, and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULen007’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant which originated from a controlled crossing between thefemale parent, an unnamed seedling, and the male parent, ‘POULskov’,described and illustrated in U.S. Plant Pat. No. 9,062 dated Feb. 28,1995. The two parents were crossed during the summer of 1995 and theresulting seeds were planted in a controlled environment in Fredensborg,Denmark. The new variety is named ‘POULen007’.

The new variety may be distinguished from its seed parent, by thefollowing combination of characteristics:

1. The seed parent has 40 petals. ‘POULen007’ has 40 to 50 petals.

2. The seed parent has a soft pink flower. ‘POULen007’ has a dark redflower.

The new variety may be distinguished from its pollen parent, ‘POULskov’by the following combination of characteristics:

1. The pollen parent has a flower diameter of 15 cm. ‘POUULen007’ has aflower diameter between 8 to 10 cm.

2. The pollen parent has a petal count of 60 petals. ‘POULen007’ has apetal count of 40 to 50 petals.

3. The general tonality of the pollen parent is Red Group 54A.‘POULen007’ is Red-Purple Group 61A.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant dark red flowers;

2. Vigorous, but compact growth when propagated both as a budded roseand on its own roots;

3. Disease resistance;

4. Exceptional fragrance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘POULen007’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter 1995 and conducted evaluations on the resulting seedlingsin a controlled environment in Fredensborg, Denmark.

‘POULen007’ was selected in the spring 1996 by the inventors as a singleplant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULen007’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in July, 1996. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULen007’ are true totype and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULen007’, as observed in its growthin a field nursery in Jackson County, Oreg. Observed plants are 3 yearsof age. Color references are made using The Royal Horticultural Society(London, England) Colour Chart, 1995, except where common terms of colorare used.

For a comparison, several physical characteristics of the rose variety‘POULisab’, a rose variety from the same inventors described andillustrated in U.S. Plant Pat. No. 12,825 dated Aug. 6, 2002 arecompared to ‘POULen007’ in Chart 1.
